I seem to be one of the many affected by the bug, mentioned
here on the wiki, that makes it impossible to unlock Hero Battles without using a PvP character to unlock it first. Thing is I have ten character slots, all used, and I won't delete any of them to make a PvP character. Each of them has far too much work invested in them and I'm not going to sign any of their names into that dreaded Delete box, it's akin to killing a friend I tell you! Nor do I really want to spend $10 more on another character slot.
So, how do I unlock Hero Battles? I'm not big on PvP in general but I'd like to try this place out. Does anyone still have one of those pre-release Nightfall packs just laying around?
